United States Patent 3,162,483 RSCKER CHAER l YET- I T=-CUSETN SEAT QQNSTRUCTIQN Peter S. Fietcher, Delray Beach, E13,, assignor to Anton Lorenz, Boynton Beach, Fla. Filed 3m. 16, 1961, Ser. No. 82,85 2 9 Claims. (Cl. 297 -89) The present invention relates to improvements in reclining chairs, and in particular to a rocker type of reclining chair which includes a leg-rest movable between a retracted position and an extended, leg-supporting position. The chair has a first or normal sitting position with the leg-rest retracted and may be rocked in this position, and a second sitting position with the leg-rest extended and in which the chair may also be rocked.

In reclining chairs and rocker chairs of the aforementioned type, the movement of the leg-rest is achieved by movement of the seat and back-rest relative to the chair frame. The arms of the chair are conventionally made as part of the chair frame, resulting in rearward movement of the seat relative to the arms. Such movement makes it impossible to incorporate in the chair a T-cushion or a seat having a T-shape design.

Modern styling requirements often call for the use of T-cushion construction of chair seats, by which is meant a seat which in plan View has a generally T-shape. The front end or" the seat has laterally-projecting portions at its sides, which portions overlap or extend across the front of the chair arms. Such T-cushion styling may be utilized in the seat itself or in a loose cushion resting on the seat.

To conform to such styling requirements, it is desirable to employ T-cushion type seats or loose T-cushions in chairs of the automatic reclining type or in rocker chairs of the reclining type. This is not possible where the seat moves rearwardly relative to the chair arms because the arms block rearward movement of the laterally-projecting portions of the T-cushion.

It is an object of the present invention to overcome the aforementioned difiiculty by providing a novel chair construction which permits the chair arms to be made as part of the seat and back-rest structure, whereby the seat does not move relative to the chair arms. The seat may thus have a T-cushion type construction or may be covered with a loose T-cushion.

In accordance with the invention, there is provided a chair having a body-supporting structure including a backrest, a seat of the :-cushion type, and chair arms all formed rigidly with each other. The body-supporting structure is mounted on a rocker member, which in turn is mounted for rocking movement on a base. The control means which mounts the body-supporting structure on the rocker member is so arranged as to move the bodysupporting structure rearwardly automatically relative to the rocker member from a first stable sitting position to a second stable sitting position. The chair also includes a leg-rest mounted for movement between a retracted position beneath the seat and an extended position forwardly of the seat, in response to movement of the bodysupporting structure relative to the rocker member. lvlanually-releasable locking means are also provided to hold the chair in its first stable position wherein the bodysupporting structure may be rocked on the base with the leg-rest retracted. When the locking means is released, the body-supporting structu e automatically moves to the second stable position wherein it may be rocked on the base with the leg-rest extended and supporting the outstretched legs of the occupant.

Another object of the invention is the provision of a chair of the character described in which the seat control means is so arranged as to cooperate with the center of gravity of the body-supporting structure to move the latter rearwardly automatically upon release of the locking means, thus eliminating the normal requirement that the occupant push upon the chair arms to start the rearward movement of the seat and back-rest.

A further object of the invention is the provision of a chair of the character described in which the leg-rest actuating means is so arranged and constructed as to cause the leg-rest to be moved to its extended position in response to a small rearward movement of the body-support ing structure.

Additional objects and advantages of the invention will become apparent during the course of the following specification when taken in connection with the accompanying drawings in which:

FIG. 1 is a side elevational view, with portions broken away and shown in section, of a rocker chair made in accordance with the invention and shown in its first stable sitting position with the leg-rest retracted;

FIG. 2 is a central longitudinal section through the chair in the position of FIG. 1;

FIG. 3 is a section similar to FIG. 1, but showing the chair in its second stable sitting position with the leg-rest extended; and

FIG. 4 is an enlarged section taken along line 4-4 of FIG. 1 and showing the locking mechanism of the chair in bottom plan view.

Referring now specifically to the drawings, there is shown in FIGS. 1-3 a rocker chair constructed in accordance with the present invention and comprising a base 12, a rocker member 14 supported on the base 12, and a. body-supporting structure 16 mounted on the rocker member 14.

Unlike the usual reclining chairs or rocker chairs of the reclining type, the body-supporting structure 16 in accordance with the present invention includes a seat, backrest, side frames and chair arms all formed rigidly as a single unit. Specifically, the body-supporting structure 16 includes a pair of side frames 18 and 2% which are spaced from each other and are interconnected by cross-bars or braces 22, 24, 2d and 23. Each side frame 13 and 20 has an upper portion 3% of lesser length than the front-torear dimension of the chair and forming a chair arm. At its rear end, each side frame 18 and 2i? is formed with an upstanding rigid post 32 forming the side of a back-rest frame. This frame is padded and covered with fabric, leather, or the like, to provide an upholstered back-rest 34. The cross-bar 22 serves to support the springs in the back-rest and also for tacking the back-rest cover.

The cross bars 24 and 28 serve as a support for a rigid seat platform 35 which is rigidly connected therebetween. The platform 36 supports an upholstered seat 38, which in the illustrative embodiment herein is in the form of a loose T-cushion. The term T-cushion in the furniture trade means a cushion which, in plan view, presents a T-s ape, having at its front end laterally-projecting portions which overlie the front edges of the chair arms. Thus, when viewed from the front, the T-cushion has the appearance of extending from one side edge of the chair to the other. The seat 33 is in the form of such T-cushion; and has front end portions 38a which project laterally outwardly from the side edges of the seat body. It is tobe understood, however, that instead of being in the form. of a separate cushion, the seat 38 may be formed integral 1y with the upholstered back-rest 3%, but would still be:

made of the same T-shape.

A frame member extends transversely inwardly from the front edge of the upper arm portion 30 of each side frame 18 and 2d. These frame members are spaced rearwaidly of the front end of the chair and extend in wardly to points adjacent the side edges of the seat 38. The laterally projecting portions 38a of the seat extend across the forward surfaces of the respective frame members 40 as indicated in FIG. 1.

The body-supporting structure 16 also includes at each side a linkage mounting rail 42, the ends of which are secured to the cross-bars 26 and 28. Each rail 42 extends from the front to the rear of the chair and is preferably spaced inwardly from the adjacent side frame to provide; room for the rocker springs, links, etc. of the chair.

The base 12is illustrated in the form of a pedestal having aplurality of legs 44 which extend radially and downwardly from a swivel assembly 46. The swivel'as-- sembly 46'is of conventional construction and comprises a stationary Iplate 48 serving as a stationary racewayandi secured to legs 44, and a movable plate 5% serving as a 48 by a ball bearingassembly 52 of the usual type. A

- .base member. 54 is .secured tothe upper swivel plate 5% and has a rocker supporting surface 56 on its upper face- The rocker member 14 is formed by a pair of spaced rocker elements 58 and 60 located on opposite sides of the chair and connected by a cross-rail 62 (FIG. 2). Each rocker element 58. and:60 has an arcuate rocker surface:

' 64- at its. bottom edge which rests upon and engagesthe rocker supporting surface ,56'of the base member 54.

Secured to the voute'rside of each rocker element 58' .and 60 is an angle bracket 66. A similar angle bracket 68 is secured to each outer surface of the base member 54 in'align'ment with'the respective bracket 66. Between each pair of brackets .66 and 68 is mounted a .pair of tension springs 70 and 72. The ends of springs 70 and ,72 are secured to the laterally-projecting flanges of. brackets 66 and 68,. and the springs serve as means'to connect the rocker member 14 with the base member 54- the latter members to a level position of equilibrium as shown in FIGS. 1 and 2.

. A control linkage mounts the body-supporting structure 16 on the rocker member 58 for rearward movement relativeto the latter'frorn the first or normal sittingpos'ition of FIGS. 1 and 2 to the second or tiltedsitting position of FIG. 3. ,In this illustrative embodiment, the control linkage includes afront guide link'7'6 disposed in a substantially upright position and having a pivotal mount 78 at its lower end on the rocker member 58 and t a pivotal connection 61) at its upper end on the mounting rail '42 of the body-supporting structure 16. The control Y wardly and slightly rearwardly inclined position. The rear guide link 82 bass. pivotal mount 84 at its lower end on the; rockerfmernber 58 and a pivotal connection ""86 at itsupper end on the mounting rail 42.

, 'Thecontrol linkage, including the front and rearguide of gravity of the body-supporting structure 16 and the occupant is located rearwardly of the instantaneous center of rotation of the guide links 76 and 82 in the upright sitting position of FIG. 2. Releasable locking means are employed for maintaining the body-supporting structure 16 in the stable upright sitting position of FIG. 2 relative to the rocker member 14, which locking means will be presently described. When such locking means is released, the body-supporting structure 16 tends to drop into the position of FIG. 3, guided by the guide links 76 and 82. 7 With the body-supporting structure 16 locked in the stable position of FIG. 1 relative to the rocker member .14, its center of gravity establishes a stable position of .movableracewayand connected to the stationary plate 9 the rocker member 14 on the base member 54 with the springs and 72 substantially unstressed. From this position, the rigidly-locked body-supporting structure 16 and rocker member l irmay be rocked back and forth upon base'12 with the rocker surfaces 64 turning upon the rocker-supporting surface 56. The springs Hand 72 are wound with some initial tension. Whenthebodysupporting structure 16 is rocked rearwardly, the rear pair of springs 72 are contracted to relieve some initial tension and the front pair of springs 7d are expanded to increase their tension. When the body-supporting structure16 is rocked forwardly, the front pair of springs 70 are contracted and therear pair of springs 72 expanded.

The chair also includes a leg-rest 9and a leg-rest control linkage 92 mounting the leg-rest on the forward portion of the seat for movement from a retracted position beneath the seat (shown in FIGS. 1 and 2) to an extended leg-supporting position forwardly of the seat,

. as'shown in FIG. 3.

In this illustrative embodimennthe leg-rest'control linkage 92is' illustrated as including three pairs of interconnected links providing a lazy tong or scissor type of leg-rest mounting and control linkage.

. It is to be understood, however, that any other suitable type of leg-rest mounting and control linkagemay be subto provide a force against which the rocker member and body-supporting structure may be rocked, and to bring 60. linkage also includes a r earr .guide link 82 spaced rearrwardly of the front guide link 76 and disposed in an upstituted therefor, such other linkages being well-known and amply disclosed in prior patents owned by the assignee of'this application.

Specificallythe leg-rest control linkage 92 includes a first pair of links 94 and 961 having their adjacent ends connected by pivot 98, a-second pair of links 1% and 102 having their adjacentends connected by pivot W4, and a third pair of links 1% and 145% having their adjacent ends connected bypivot 110. The first link 94 of the first pair has'a pivotal mount 112 on the forward portion of the mounting rail 42, while the first link 1% of the second pair has a pivotal mount 11 5- on the rail 42 at a point spaced forwardly of the pivotal mount 112. The second link 96 of the first pair crosses over the first link 1tltlof the second pair and hasa pivotal connection 116 therewith. The forward end of the second link -96 of the first pair has a pivotalxconnection'118 to the first link 106 of the third link pair. The second link 162 of the second link pair crosses over the first link 1% 0f the third link pair and is. connected thereto at'its crossing over point by pivot 12$.v The ends of links 102 and 1118 are connected to' spaced points on the leg-rest by respective pivots 122 and 124. V

V The leg-rest actuating and control arrangement is com- ;pleted by a direct actuating link 126 which has a pivotai connection 123 at its forward end with the link 94and 'a pivotal' mount 130 on a bracket 132 aff xed to the rocker member 14.

In response to rearward movement of the body-supporting structure 16 relative to rocker member 14, the pivotal connections 112,114 of the leg- .rest mounting linkage will be displaced rearwardly and the actuating link 126 will oppose the rearward move- 1mentof the link 94 atpiv0t'128, causing the link 94 and its connected link 1% to swingforwardly and upwardly. about the respective pivotsi112 and 114 to therebymove T the leg-rest 9th from its stored position illustrated in FIGS.

'1 and 2 toJanelevated leg-supportingposition spaced. forwardly of'the seat 38, as shown in FIG. 3. V p

In the stored or retracted position of the leg-rest 9-!) shown in FIGS. 1 and 2, the leg-rest is located in a vertical position beneath the forward end of the seat 38, with its upper end portion adjacent the cross-bar 28. Locking means 136 are provided to hold the leg-rest 9%) in this retracted position and therefore also hold the body-supporting structure 16 in the stable position of FIGS. 1 and 2 relative to the rocker member 14. Said locking means 136 is illustrated in H6. 4 and includes a bracket 138 secured to the under surface of crossbar 28, which bracket 138 has an integral turned-up lug 140 forming a fixed latch element. A second lug 142 forms a movable latch element, and is secured to a rod 144. The rod 144- extends slidably through the fixed lug 14d and its end has a ring or eyelet 146 to which one end of a coil spring 148 is connected. The other end of spring 148 is secured to an anchor pin 15% afiixed to the cross bar 28 in such a manner that tension of spring 148 urges the movable lug 142 toward the fixed lug 148. An angle bracket 152 is secured to the under surface of leg-rest 90 and is so positioned that its leg 152a will he slid between the lugs 14% and 142 and retained by the friction lock formed by said lugs. The lugs 14% and 142 have respective flared terminal portions 148d and 142a at their outer ends which act to guide the bracket flange 152a between the lugs 14% and 142. FIG. 4 illustrates the position of the leg-rest 9% in which the bracket lug 152a is about to enter the lugs Edi) and M2, just before the leg-rest arrives at its fully-retracted position.

The free end of rod 144 is bent over and extends through a hole 154 in one end of a lever 156 to provide a pivotal connection with said lever 156. At a point closely spaced from the hole 154, the lever 156 is mounted by pivot 158 on a bracket 160 afiixed to the cross-bar 28. The remainder of lever 156 defines a long lever arm, the free end of which is connected by pivot 162 to the end of a link 164. The link 154 is mounted for longitudinal sliding movement on the linkage mounting rail 42, and for this purpose has a longitudinal slot lied which slidably receives a pin 168 aflixed to said rail 42. A rod 17%) is secured to the end of link 1164, and at its free end the rod 170 carries a push-button 172. The push-button 172 extends slidably through an opening 1'74 in the chair side frame 18, which opening 174 is bordered by a metal ring E 6 secured to the outer surface of side frame 18. The ring 176 provides a sliding bushing for the push-button 1"72 and also serves to prevent unravelling of the fabric (not shown) with which side frame 13 is covered.

With the leg-rest 99 in its fully retracted position of FIG. 1, the bracket leg 152:: is clamped tightly between the lugs 140 and 142 and is frictionally retained thereby through tension of spring 148. The locking of the legrest in its retracted position also looks the body-supporting structure 16 in its stable position of FIG. 1 relative to the rocker member 14, and the body-supporting structure may be rocked upon the base 1 in the manner previously described.

When the occupant of the chair wishes to assume a more comfortable position with his legs supported in outstretched condition, suitable for viewing television, reading, or the like, he merely presses push-button 172 inwardly. This causes link 164 to slide inwardly on rail 42, turning lever 156 about pivot 158, and drawing rod in the direction of the arrow in FIG. 4. This sliding movement of rod 144, against tension of spring 148 separates the movable lug 142 from the fixed lug 140 and releases the bracket leg 152a carried by the leg-rest 43 so that the latter is freed to move to its extended position.

The body-supporting structure 16 under the biasing force of its center of gravity and that of the occupant will then move automatically to its second stable position of FIG. 3, guided by the guide links '76 and 82.. When the pushbutton 172 is released, the tension of spring 148 will return it to its projecting position and also move the lug 142 back toward fixed lug 14%) so that the lugs are again positioned to receive and frictionally retain the bracket leg 15241. The slot 165 is sized to limit movement of the push-button 172 so that it does not project too far out wardly of the side frame 18 and cannot be pushed too far within the opening 174.

When the body-supporting structure 16 is moved rearwardly upon rocker member 14 by the guide links 76 and d2, its rearward movement is halted by engagement of the under surface of the rail 42 with a rear portion 173 of rocker member 14, as shown in FIG. 3. In this position, the body-supporting structure 16 is tilted rearwardly slightly relative to rocker member 14. Since the legrest Qt} is extended, however, and is supporting the outstretched legs of the occupant, the center of gravity of the body-supporting structure 15 is shifted forwardly, causing the rocker member 14 to tilt forwardly on the base member 54, as can be seen by comparing FIG. 3 with FIG. 2. This forward tilting movement of rocker member 14 brings the body-supporting structure 16 to the balanced or stabilized position of FIG. 3 in which it is approximately at the same pitch relative to the base 12 or floor surface as it was in the sitting position of FIGS. 1 and 2. The occupants body is therefore disposed in approximately the same sitting position, except that the leg-rest is extended.

With the chair in the stabilized position of FIG. 3 with leg-rest g9 extended, the occupant may again cause the body-supporting structure 16 to rock upon base member 12 in the manner previously described and to the extent permitted by the springs 70 and 72.

To return the chair from the position of FIG. 3 to the position of FIGS. 1 and 2, it is only necessary for the occupant to push downwardly with his legs upon the legrest causing said leg-rest to move back to its retracted position, wherein the bracket leg 152a will again be grasped and retained by lugs and 142.

It will be appreciated that since the seat, back-rest, and chair arms are made in one integral unit as the bodysupporting structure 16, there is no rearward movement of the seat relative to the chair arms, as is customary in reclining chairs, and a T-cushion construction can be used in the scat. Since, however, with this arrangement the occupant cannot start the initial rearward movement of the seat and back-rest by grasping the chair arms and applying rearward pressure to the seat and back-rest in the normal manner of conventional reclining chairs, the body-supporting structure of the present invention is biased rearwardly so that it automatically begins its rearward movement. in the illustrated embodiment, this biasing force is provided by the arrangement of guide links 76 and 32. A releasable locking arrangement is thus pro vided to hold the body-supporting structure 16 in its normal sitting position against this realwvard biasing force.

While a preferred embodiment of the invention has been shown and described herein, it is obvious that numerous additions, changes and omissions may be made in such embodiment without departing from the spirit and scope of the invention.
